China plastic blow molding products supplier, In the extrusion blow molding (EBM), Plastic is melted and extruded into a hollow tube, then, seel it in a cooling metal blow molds, The air is then blow into the priest's body, causing it to expand into the shape of hollow bottles, containers, or parts.

We manufacture blow molding products, such like plastic bottles, shampoo bottles, milk bottles, plastic tubs and fuel containers. Blow molded plastic part’s features are hollow and thin-walled. Our facilities have great experience in supplying the US and the European markets, as well as Australian and Mexican markets. Blow molding (BrE moulding) is a specific manufacturing process by which hollow plastic parts are formed and can be joined together: It is also used for forming glass bottles or other hollow shapes. In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding. The blow molding process begins with melting down the plastic and forming it into a parison or in the case of injection and injection stretch blow moulding (ISB) a preform. The parison is a tube-like piece of plastic with a hole in one end through which compressed air can pass.

The parison is then clamped into a mold and air is blown into it. The air pressure then pushes the plastic out to match the mold. Once the plastic has cooled and hardened the mold opens up and the part is ejected. The cost of blow moulded parts is higher than that of injection – moulded parts but lower than rotational moulded parts.

Mulan manufacturing group has a very professional injection blow mold factory, and can realize the one-stop service, from the design of the blow mold, the blow mould making, plastic injection blow molded products, support the use of injection molding parts or metal parts, surface printing,Mulan manufacturing group can help customers to achieve. Extrusion blow molding - An extruder uses a rotating screw to force the molten plastic through a die head that forms the parison around a blow pin. The parison is extruded vertically between the two open mold halves, so they can close on the parison and blow pin. Pressurized air flows through the blow pin to inflate the parison. This is the most common type of blow molding and is used to manufacture large quantities of relatively simple parts. Injection blow molding - The molten plastic is injection molded around a core inside a parison mold to form the hollow parison. When the parison mold opens, both the parison and core are transferred to the blow mold and securely clamped. The core then opens and allows pressurized air to inflate the parison. This is the least commonly used method because of the lower production rate, but is capable of forming more complicated parts with higher accuracy. Injection blow molding is often preferred for small, complex bottles, such as those in medical applications. Stretch blow molding - The parison is formed in the same way as injection blow molding. However, once transferred to the blow mold, it is heated and stretched downward by the core before being inflated. This stretching provides greater strength to the plastic. Stretch blow molding is typically used to create parts that must withstand some internal pressure or be very durable, such as soda bottles.

Mulan has been producing blow-molding products for more than 10 years and produced more than 1000+ kinds of products. However, in order to guarantee the copyright of customers, we are not convenient to display on the website. Welcome to China.
